irregular (and so sinuses), long and short, acute and blunt, 

 margins sub-repand with minute denticulations about apex ; 

 anterior margin much arched ; posterior nearly straight, a 

 little excised. Cells sub-orbicular-oblong, distinct, guttulate, 

 obscure. Stipules patent, recurved, sub-quadrate, broadest at 

 base and closely approaching bases of leaf but not joined, 

 top truncate, sub 4-tid, each coarse tooth (or small lobe) again 

 serrate, sides denticulate. Cells narrow oblong and clear at 

 margins, smaller and more compact (yet distinct) at centre 

 and base. 



Hah. Woods near Lake Waikare, County of "Wairoa ; 

 1888 : Mr. H. Hill. 



Obs. Only three specimens received, mixed with other 

 Hepaticce. 



2. M. vulcanicum, sp. nov. 



Plant stout, dichotomously branched, (?) 2in.-3in. long, 

 1|- lines wide, dark-coloured, fiagelliferous ; flagelliP wiry, 

 rigid, branched. Leaves brown, thickish, rather opaque, 

 falcate, close-set, narrow oblong, broadest at base, with their 

 slightly-produced anterior margins near base a little over- 

 lapping ; tips truncate with many acute teeth, the three 

 principal ones large and sub-spiny ; the lateral margins 

 slightly denticulate below apex ; anterior margin a little 

 arched ; the posterior one slightly incurved, and excised at 

 an obtuse angle near base. Cells distinct, guttulate in longi- 

 tudinal lines, alike tln-oughout. Stipules distant, sub-quad- 

 rate, much recurved, their tips and sides largely and irregu- 

 larly toothed inclining to spiny. 



Hab. Among small tufts of other Hcpaticce and mosses, 

 on the ground, Mount Tongariro, County of East Taupo; 1887 : 

 Mr. H. Hill. 



Obs. A species near to M. olivaceur.i, Col. ("Trans. N.Z. 

 Inst.," vol. xix., p. 290). 



3. M. smaragdinum, sp. nov. 



Stems rather stout, cellular, lin. long, sub-liabellately 

 branched ; branches forked, pinnate, very leafy throughout, 

 much flagellate ; flagelkc flexuous, stout, scaly. Leaves dark 

 grass-gi'een, shining, numerous, imbricate, oblong, dimidiate ; 

 tip 2-lobed, the upper lobe larger, sinus wide ; margins entire 

 but slightly uneven, the anterior one arched excised at apex, 

 the posterior nearly straight. Cells large, very regular, sub- 

 orbicular with minute interstitial orbicular cellules at their 

 angles, oblong and a little larger at extreme base. Stipule 

 free, distant, appressed, sub-quadrate, 3-fid, lobes stout, 

 obtuse ; cells as in leaves. Male inflorescence near base of 

 stem, pedicelled, 4-5 nearly together : perigouial leaves very
